The correct answer is: D. all of the above

A macromolecule is a large molecule present in the cell, composed of a huge number of monomer units with the various functions. There are four main groups: proteins (monomers are amino acids), nucleic acids (monomers are nucleotids) , lipids (monomers are free fatty acids) and carbohydrates (monomers are simple sugars such as glucose).

Some of their functions:

• Provide structure on the cellular levels-lipids (phospholipids) are the main components of the cell membrane;

• store energy-starch is energy source in plants;

What’s Newton’s first law
Klio2033 [76]
Newton’s first law had to do with inertia, which is a property that explains that something in motion will continue in motion unless stopped by a force of some sort.

“An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.”
